Author: Jon

For the top-level wiki page, the <span class=parentlink is generated but its empty.

This was reported in Debian in 2009 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=523693

I actually closed it recently, because I disagreed with the suggested patch. However, there's a more agreeable fix: just wrap the parentlinks section in a test of HAS_PARENTLINKS.
